Description

Device for draining water, e.g. B. steam water, from a Pressure line. The simplest device for discharging water, e.g. B. steam water, consists of a pressure line in a siphon-like, finite k = ondensat filling loop, in whose free = n legs (with the = overflow) the adjusting Condensate column to the gas or vapor pressure prevailing in the other leg (read equilibrium holds while the condensation, which is constantly flowing in, is pushed out will. While the dimensions of such loops for low pressure lines in keep controllable limits, this is not the case for high pressure lines, since the loop length is here in the order of magnitude of about 100 m at 10 atm. would have to move, which means that they can only be used using existing shafts is, as here, too, the investment costs are very high.

One already has the one that forms in the leg of a siphon Condensate column used to control a pressure element together with a closing valve: the However, related facilities have the peculiarity that the controlling The liquid column is set up to a certain extent above the closure organ got to, so that this itself a considerable distance below the container to be drained to lie k; xnitit. However, this results in spatial restrictions, e.g. B. if Preßluftleittlligen in mines or steam lines in machine houses drained should be, where from the outset only limited building plans are available. Here the actual device would often have to be housed in a pit, with which it would itself be exposed to pollution, not observed and not waited for could be. The practical experience with the often poorly working condensate conductors but make good maintenance and testing of such devices appear necessary.

The invention follows your main idea, the advantages of such siphon-like loops: for the drainage of the linlirleiisats to be attached to the however, to eliminate disadvantages arising from their excessive length, and this is because (let a piston (or a Bending skin), four on one side under (partially undiminished gas pressure is set, while on the other hand the gas pressure minus the K> ndensatsäule acts, which adjusts itself in the free leg of the loop. This achieves (Let the actual Mechanisintis, the atis your pressure member and the: nit it directly connected final velitil ordered, (light under (part to dewater- (part vessels (lzolirleittiiig (-n) can be attached, while the loop: as a unenipfindfiches and the observation hardly needed element, if necessary, also under the floor can be laid immersed in a pit.

The invention is in one embodiment in Fig. R in one, shown in Fig. z in the other end position, Fig. 3 represents a horizontal arrangement represent, -% välirend Fig. i a and .T allow a peculiarity to germinate.

All the steam or gas pipes are connected to the loop ir, which has the overflow 1z for (the condensate; this loop is filled in its lower part by the condensate Line 13 to your housing 14, in (the piston 15 moves, which finitely with the help of a valve cone 17 is able to close the hole in a throttle disk 16, which is connected between the condensate-filled leg of the pipe rr and your free overflow 1a. The column in this way places the pressure of steam or gas on its lower surface under reduced pressure, while on its surface it is reduced under the pressure of steam or gas designed as a kind of siphon, but in such an arrangement, no large p siti can set up here or a negative condensate column; namely, it should only a liquid seal must be formed and maintained, which prevents the vapor gas from directly reaching the lower surface or piston while the unhindered pressure mpfes or D @ should take effect. For the purpose of the leg, the connection to the grinder is designed in such a way that condensate can flow in to keep the siphon constantly full, but while an excess is always returned to the line. In this way, it only needs to be sealed against liquid, so that its installation is possible with as much play, its constant mobility appears to be guaranteed: even pressing through the condensate does not play a decisive role. the piston r5, (let Kol-17 ben hole 12 for 'even 17, 16 only liquid fluid caps 2 by way -the reach the liquid column, reduced difference in pressure 1.9.

In the condition shown in Fig `` '' flow out interrupted, thus preventing emptying of the loop tt, and prevents (let Dainpf or gas blow out in the siphon i gas can neither one after the other to the valve, 1 the newly added condensate rises in one leg, which increases this rise on the two surfaces of the necklace, even with large, sudden Not allowing the ingress of condensate to go ahead too suddenly can also be done by placing an appropriate corrugated container in place for the all-conductor effect. If rlie Fliissil; l i1 has risen by a certain amount, then the K (üh @ n falls downwards under its own weight opens a glass hole in the throttle disc r f5, so (1a13 j 1-r_1 t under the excess gas pressure (read Kori (lcnsat n = down to L; the overflow is conveyed upwards, the resistance of the liquid in the hole of the throttle disc r <secures clagegt: n, about a disproportionate amount of water from t: dm>'' is thrown out brightly to drained condensate, the piston i 5 is moved upwards to close the through hole again.The fact that these processes take place in constant alternation and the piston 15 oscillates back and forth between .eine end positions is valuable in this respect as this ensures the necessary sensitivity of the device.While in the steady state there would be the danger (let the piston fix in its reverse position, it prevents the formation of deposits on its constant back and forth movement n and ensures its mobility. The circumstance (let the upper effective piston surface uni (the measure of the \ -e, itile seat be reduced in the moment of closing, whirl in the sense, (let the water column h first shrink to a certain minimum before the coll; en fully loosens its seat. This guarantees that the piston will immediately move to its other end position (la now suddenly an increase in all effective piston area occurs.

If the Velltillcegel 17 is provided with a needle-like extension 1g, which passes through the bore of the throttle plate 16, s ;, is also iiiimer again this opening is fully cleared of c @ üvaigcn blockages.

Another possibility to bring about opening to facilitate the opening is created by arranging a non-return valve finite Schwinriner 20 in the line 13. If the liquid level in loop ii rises above branch 13, the valve closes the non-return valve which he keeps open without liquid (for his body).

In connection with the above-mentioned guiding of the piston with play and the constant up and down movement ensured by the bilateral liquid closures, this rotary movement appears as a means to guarantee the mobility of the piston under all circumstances (Fig. ...).).

The device is intended especially as a water separator for steam and Compressed air lines are used, but other liquids can also contain gaseous elements separate.
